RADIATOR CONSTRUCTION.

Application led. August 25, 1921. Serial No. 495,344.

To all whom t may concern.'

Be it known that I, OsoAr. ANDiiiasoN, a citizen of the United States, and a iesident of the city of Clinton, in the county of De Witt and State of Illinois, have invented certain new and useful Improvements in Radiator Construction; and I do hereby declare that the following isa full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification.

Considerable ditticulty has heretofore been experienced by automobile owners and repair men in connection with leaky and defective radiators, especially those supplied with the cheaper types of cars, it having been found, in many cases, almost iinpossible to repair a punctured radiator'tube without completely rebuilding the radiator,

which, of course, was the source of considerable trouble and expense. This, of

course, is due to the fact that the topv and bottom reservoirs of the radiator are connected by vertical tubes through which the water circulates, and a set of cooling flanges or radiating tins, consisting of a number of longitudinal plates having holes therein through which the tubes pass, are associated with the said vertical tubes, the horizontal plates providing a large cooling or radiating surface.

One of the objects of this invention, is, therefore, to provide an automobile radiator in which the connecting tubes are made in a number of readily detachable banks or sections each consisting of a series of tubes which are easily accessible.

Another object of this invention is to provide a new and improved type of cooling flange or tin which does not extend entirely across a horizontal section of the radiator and which, therefore, will not have to be cut in order to enable a. repair man to locate and reach a leaky tube.

A still further object of the invention is to provide a new type of radiator fin which is connected with only one tube or set of tubes and which therefore can be readily disassembled and taken out of the radiator structure.

Other and further objects of this invention will be apparent from the disclosures in the accompanying drawings and speciication.

The invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described.

On the drawings:

Figure l is a front elevation of my improved type of radiator shown as applied to a well known type of automobile.

Figure- 2 is aV sectional elevation of the same taken at right angles to Figure l.

Figure 3 is a detail sectional view taken at right angles to Figure 2.

Figure 4t is a horizontal section taken on the. line 4 4 of Figure 3.

Figure 5 is a detail plan view of aV p0rtion of the bottom of the upper reservoir.

As shown of the drawings:

The reference numeral 10 indicates an a automobile radiator of a common shape and type having my improved tubes and radiating fins incorporated therein. The radiator lO is mounted in an ordinary manner upon the spring l2 and front axle 14: of

the car. This radiator comprises an upper reservoir 16, a lower reservoir 18, and the usual vertical connecting tubes 20, upon which tubes are arranged radiating fins 22 according to my invention. These radiating u and they may be soldered or brazed to the tubes at these points if desired, in order to form a more perfect heat conducting joint.

At the top of each bank of tubes 20, usually four, in number, is soldered or brazed a perforated plate 26, made of such a length as to extend across the width of the radiator and acommodate the four tubes. Of course, this number may be varied if desired. Each of the plates 26 has a downwardly extending edge 28 adapted to underlap the edge of the adjacent plate, as shown in Figure 3. At the bottom of each set of tubes 2() is fitted a corresponding plate 30, having a similar overlapping edge 32.

The reservoirs 16 and 18 have inwardly extending horizontal end portions 34 and 36 which are adapted to co-act with the plates 26 and 30, in order to form the bottoni of the upper reservoir and the top of the lower reservoir respectively. These plates may be attached to each other by any suitable means as by soldering, brazing or the like. It will be seen trom an inspection of Figures 2 and 3, that two corresponding plates 25 and 30 are adapted to accommodate a banket four tubes, together with the Lipper and lower plates 26 and 30 and the two cooling flanges 22 form a complete section which is removable as a whole.

The operation is as follows:

Vhenever one or several ot the tubes 2O become leaky on account of a puncture in the same caused by freezing or otherwise, the section containing the detective tube or tubes can be removed in a very short time by merely passing a hot soldering iron along theV joint formed between the overlapping member 28 and the adjacent portion of the plate 26 ot the next bank, and aroundV the overlapping joints Ytermed by the offset member 32 lying over the adjacent portion of the next plate 30. After the solder has been loosened along these joints, the entire section lcan be slidably removed, then thefjoints between the tubes 20 and the fins 22 can be heated, and the tins removed, thereby vmaking a repair possible with a minimum of trouble and effort.

Also, in the case of only oneY ot the tubes becoming leaky, and especially it the tube is either inthe front or the rear ol the radiator, and therefore more readily accessible, the entire section need not be removed, but portions of the radiating tins or cooling iangesQQ may be readily loosened by merelyA touching a soldering ironto the junctures between the semi-circular parts Q-t ot the Vradiating fins and the tube 20, at which pointthey are soldered together. After the solder has been melted away. one set of radiating tins can be readily removed or pushed to one side without disturbingv any of the adjacent fins, and upon its removal, the soldering iron may be readily inserted in the space between the tubes especially if the adjacent radiating tins between two sections have both been removed.

It will be seen that herein is provided a radiator for automobiles which can be readily and easily repaired in case of leaks in the'` top and bottom sections 'are first melted apart, the section removed,` then the ins melted ot the punctured tube, it.. necessary, finally the puncture in the tube is repaired and the radiating fins and sections are soldered back again in position completing the job. 'l Y I am aware that numerous details oi2 construction may be varied through a wide range without departing trom the principles et this invention, and I therefore do not purpose limiting the patent granted otherwise than necessitated by the prior art.

I claim as my invention:

l. A radiator for automobiles including an upper reservoir, a lower reservoir, a plurality of sets of removable plates comprising the bottom and top of the `upper and lower reservoirs respectively`v a series of vertical circulating tubes connecting each set ot removable plates, and a set ot removable cooling ilanges on each series ot' tubes, said flanges being arranged so that each series ot tubes may be removed independent ot the others.

Q. An automobile radiator section comprising a top plate, a bottom plate, a series of vertical tubes connecting said plates, and

a horizontally corrugated plate on either #i subscribed my naine in the presence ot two 1 'i subscribing` witnesses.
